THSD7A and infection: Consequently microarray platform (3 Normal control chips Vs 3 shRNA Thsd7a chips) was used to examine Eca 109 cell line after infection with lentivirus which could express Thsd7a-shRNA with the aim of identifying genes exhibiting remarkable differential expressing status (P < 0.05 and absolute fold change (FCAbsolute) > 2), including upregulated genes and downregulated genes (Figure 7A).
